I have an HP Pavilion laptop that I got in July 2007 and it started having issues with the wireless adapter in January 2008. From what I understand it was due to heat from the Athlon 64 X2 processor, and finally one day in April 2008, it overheated so much, that the video card fried. Sent it back to HP (was still under warranty) and they had to replace the motherboard and video card. Thankfully they did it for no cost, including shipping,but they had to wipe the hard drive (for some reason). Thankfully, I backed it up before sending it in.
